Hi Airshipers, We successfully deployed the aiab from treasuremap for a while and activated the Prometheus monitoring. Instead of deploying again from Genesis, Now I try to use the site update mechanism: (cf. https://airship-treasuremap.readthedocs.io/en/latest/config_update_guide.htm... ) - Pegleg lint + collected yaml generation - Shipyard create and commit docs (No error) In fact we only modify the initial site by adding a parameter in Prometheus Chart using Deckhand substitution mechanism. The site syntax seems Ok and has been committed, but the update_site action fails: Name: update_site Action: action/01DPTGTT31Y7CVYFGZYJVDV402 Lifecycle: Complete Parameters: {} Datetime: 2019-10-10 09:43:37.826039+00:00 Dag Status: success Context Marker: 649459d0-239e-4a86-ad23-73daa304b588 User: shipyard Steps Index State Footnotes step/01DPTGTT31Y7CVYFGZYJVDV402/action_xcom 1 success step/01DPTGTT31Y7CVYFGZYJVDV402/dag_concurrency_check 2 success step/01DPTGTT31Y7CVYFGZYJVDV402/get_rendered_doc 3 success step/01DPTGTT31Y7CVYFGZYJVDV402/deployment_configuration 4 success step/01DPTGTT31Y7CVYFGZYJVDV402/preflight 5 success step/01DPTGTT31Y7CVYFGZYJVDV402/validate_site_design 6 success step/01DPTGTT31Y7CVYFGZYJVDV402/drydock_build 7 failed step/01DPTGTT31Y7CVYFGZYJVDV402/armada_build 8 upstream_failed step/01DPTGTT31Y7CVYFGZYJVDV402/decide_airflow_upgrade 9 upstream_failed step/01DPTGTT31Y7CVYFGZYJVDV402/verify_site 10 success step/01DPTGTT31Y7CVYFGZYJVDV402/prepare_site 11 success step/01DPTGTT31Y7CVYFGZYJVDV402/skip_upgrade_airflow 12 upstream_failed step/01DPTGTT31Y7CVYFGZYJVDV402/upgrade_airflow 13 upstream_failed step/01DPTGTT31Y7CVYFGZYJVDV402/armada_get_status 14 None step/01DPTGTT31Y7CVYFGZYJVDV402/verify_nodes_exist 15 failed step/01DPTGTT31Y7CVYFGZYJVDV402/create_action_tag 16 success step/01DPTGTT31Y7CVYFGZYJVDV402/armada_post_apply 17 None step/01DPTGTT31Y7CVYFGZYJVDV402/ucp_preflight_check 18 success step/01DPTGTT31Y7CVYFGZYJVDV402/deployment_status 19 success step/01DPTGTT31Y7CVYFGZYJVDV402/deckhand_validate_site_design 20 success step/01DPTGTT31Y7CVYFGZYJVDV402/drydock_validate_site_design 21 success step/01DPTGTT31Y7CVYFGZYJVDV402/promenade_validate_site_design 22 success step/01DPTGTT31Y7CVYFGZYJVDV402/armada_validate_site_design 23 success step/01DPTGTT31Y7CVYFGZYJVDV402/prepare_and_deploy_nodes 24 upstream_failed step/01DPTGTT31Y7CVYFGZYJVDV402/final_deployment_status 25 success step/01DPTGTT31Y7CVYFGZYJVDV402/armada_get_releases 26 None As I previously already faced such this error when activating Prometheus, I wonder whether the aiab site allows the update_site action or if it contains some specific scripted actions that prevent running this action?
